I visited the telegram group of this project and some of the information I got was that until now the coins had never been distributed and the project was closed without further development. is that true? anyone can explain to me.

I have read a lot of times that this project is scam. But some people said that they had already received their tokens. So I don't know what to think.
How do they receive coins if this is indeed fraud because I joined this bounty. but until now they have never explained when tokens will be sent with a certain time. disappointing thing.
Admin in telegram chat says that distribution of tokens for bounty campaign is going. But a lot of bounty hunters said that they don't need these tokens, as this project had been closed. I don't know whom we should believe.
There are more rumors, i waiting official info about team for publish here, this thread only published here but i'm not a team member. I have received a note where first CEO have abandoned the team, and new CEO decided abort the project and refund the investors. Please see on this on original telegram group official chat and official annuncment here:
